Hey guys doing a ls1 t56 swap in a 2000 mustang. Just curious how far my driveshaft yoke needs to go into my t56 trans. Is 2.5 inches enough? And also if anyone knows how deep a yoke can go. I found an aftermarket yoke that would go 5.5 inches into the trans. Is that to deep and would it bottom out?

Thanks! Jason

Or of anyone has a stock yoke that they could measure for me. Barrel length and end of barrel to center of u joint would be awesome! Thanks

I have an OEM Aluminum Driveshaft sitting in my garage. I can take some measurements tomorrow night and post them if no one has by then.

That would be great! I appreciate it

The first pic is from the base of the balancer to the end of the input shaft. The second pic is from the centerline of the U-Joint to the end of the input shaft. I don't know how much room there is for an input shaft on a T-56 or if 2-1/2" will be enough, but maybe these will help you out a bit.

Thank you very much. That's the problem I'm having. I have found two yokes that I can order. One is 3 5/8 barrel which leaves only about 2 1/2 inches in the trans. Other is a 6 inch barrel and that will put 5 inches in the trans. I would go with the larger if I knew 5 inches would fit but i don't know if it will bottom out.

If you have a solid axle you want about 3/4" to 1" more slip at ride height. With suspension droop it will disengage more. The short yoke is probably for cars with a fixed diff that doesn't travel up and down with rear suspension travel. With a live axle like a mustang would have you want the long one.
